Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31513062, here are decompositions:

5 + 31513057 = 31513062
13 + 31513049 = 31513062
29 + 31513033 = 31513062
59 + 31513003 = 31513062
71 + 31512991 = 31513062
103 + 31512959 = 31513062
149 + 31512913 = 31513062
193 + 31512869 = 31513062

Showing the first eight; more decompositions exist.
